Punch list items raised at DoF Meeting 2019-07-08 + Updates for 2019 Sept. FHIR CAT & WGM:

"To do" items for PoCD Implementation Guide updates in next version

#1 See "Excerpt from Stefan Karl's ..." below 

  1. Update per FHIR R3.5 → R4.0 → current build w/ Version notes
  2. HL7 V2 → FHIR mapping: Build additional page for mapping from HL7 V2 (IHE PCD Device Enterprise Communications device observation) to FHIR PoCD Implementation Guide
    1. NOTE:  Proposed DEC FHIR Option that will leverage / inform the IG V2 mapping & FHIR messaging content
  3. IEEE 11073 Service-Oriented Device Connectivity (SDC) to FHIR PoCD IG -
    1. (Bjorn Andersen has a student, Cora Brenahahn, working on 11073-10207 BICEPS FHIR "profile" in Simplifier (this material will require some conversion from the Simplifier form if we continue to use traditional IG building methods)
    2. (Todd Cooper / Ken Fuchs / Stefan Schlichting) IHE SDPi "grouped" actors w/ FHIR 
    3. Consider SOMDA & MDPWS content as well, across all 4 key purposes
    4. Consider SDC-FHIR DAS / CDAS / Delegation Scenarios
  4. RESTful interaction details for PoCD
  5. Short comparison w/ PHD FHIR IG
  6. Use cases: amplify, add more
  7. Examples (more examples, amplify descriptions of existing ones)
  8. Safety, Security, Privacy sections to be written
  9. Sample arrays (esp. waveforms) - details of use, example
  10. Recover text from first (Simplifier) version that were omitted form second (IGPublisher) version

Longer-term "to do" items

  • Page on use of Messaging paradigm with Device Data
  • Development of device Alert use case and supporting resources (look into similarly titled work in DaVinci group)

Near term actions:

Stefan Karl: RESTful details (3), Examples (5)

John Rhoads: HL7 V2 mapping, Messaging paradigm details, 

Excerpt from Stefan Karl's 2019-06-29 email first discussed at 2019-06-24 DoF PoCD Subgroup meeting:

This is my quick bullet list of what we need to work on:


  • Update to current version of the IG Publisher (this is kind of moving target)
  • Changes from FHIR version 3.5.0 to 4.0.0 (if any)
  • Upcoming changes (e. g. canonical URL for MDC code system)

Ballot resolution – see GForge tracker items:

  • Add use cases
  • Add capability statement
  • Consider “must support” flags
  • Provide guidance and examples
  • Other


  • Add an “Use Cases” section
  • Add an “Implementation Guidance” section
    • Creating a Device Model
    • Mapping from HL7 v2 to FHIR
    • Mapping from IEEE 11073-10201 to FHIR
    • Mapping from IEEE 11073-10207 to FHIR
    • RESTful Transfer
    • Other Transfer (?)
    • Safety Considerations
    • Security and Privacy Considerations
  • Add DeviceMetric and Observation profiles for Sample Arrays (waveforms)
  • Add tbd. Alert resource profiles and value sets
  • Make consistent examples

There are different ways how mappings could be documented: Tables in the text part of the IG, or adding element.mapping entries to the StructureDefinitions.

It may be worth looking at the 2-To-FHIR Project and David Hay’s blog post on this topic.
